Arterioportal fistula — either acquired or congenital — is a rare syndrome, which is a real challenge in gastroenterologic diagnostics. We report a case of a 76-year-old female, who was admitted to the hospital with symptoms of permanent abdominal pain and a bruit in the epigastric region. Twelve years prior she underwent Billroth II gastrojejunostomy due to a perforating duodenal ulcer, followed by cholecystectomy 6 months later. CT and MR angiography showed a fistula between the gastroduodenal artery and the portal vein. Successful treatment of the arterioportal fistula was achieved by intravascular coil embolization resulting in the resolution of the symptoms. After six years of follow-up, abdominal ultrasonography did not show any novel findings and our patient is still doing well with no recurrence.
